Abstract :
Projection onto Convex Sets (POCS) and Smart Gradient Project (SGP) method to Active Constellation Extension (ACE) are proposed in this paper. The Peak-to-average ratio in Orthogonal Frequency Division Multiplexing (OFDM) system can be reduced through the constellation extension. The experimental results have shown that the proposed method is feasible and effective.
